I’ve already spent some time with this kind of thing.
I have a number of different setups, depending on what I would want to do. For instance, I have the normal default, just for quickly trying something, A simple template for a couple of synths, and a bit of bussing, to a full setup with my common VST/is already mapped in, with Drums preconfigured, a couple of busses (reverb and delay), so all I then need is the tune.
Trouble with too many predefined things is the imagination can get stifled, and everything sounds the same. For instance, if I want to change the ‘verb to a different plug, I’m less likely to if something adequate is already mapped. If I want a different drum sound, it would be better to start with nothing there, and import something new and fiddle.
Having said that, we are creatures of habit, and if you have something that works, you use it!
